Summary

Coxsackievirus is a single-stranded RNA virus belonging to the enterovirus genus and the picornaviridae family. It primarily affects the gastrointestinal tract and is mainly transmitted via the feco-oral route. Based on its pathogenicity, Coxsackievirus is divided into two groups: A and B. Coxsackievirus group A affects the skin and mucous membranes, causing hand-foot-mouth disease in children, and coxsackievirus group B, affects internal organs, resulting in more severe conditions such as gastroenteritis, pericarditis, myocarditis, and encephalitis.
